This site concerns the practical demonstration of cryptography weakness. (If you don't like the term "password cracker", use "password recovery" instead). All software presented here illustrates four main reasons of cryptosystems untrustworthiness: application of weak algorithms, wrong implementation or application of cryptalgorithms and human factor. The main goal of this site is to explain these reasons and to convince people of the use of strong cryptography. Therefore you can't find here password "crackers" that do not use any weakness, such as http, POP3 or SMTP password crackers, Hotmail password cracker, etc. All password recovery utilities are manually tested and only the best are included. If you know better password recovery software, you may submit it to the catalog.
